2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Bought a car here and was elated to have Damion guide me
Bought a car here and was elated to have Damion guide me through the whole process. From the first call to the test drive and finalization of the sale he was amazing! Never did i feel pressured and he was always there by my side guiding me to make the best decision!!!! Thanks Damion!!!!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Sansone Hyundai did the right thing.
Sansone Hyundai did the right thing. My son and I purchase a certified pre-owned 2022 Hyundai Tuscan on July 15,2024. During the courtesy oil and filter change in January 2024, the service technician indicated that all four tires needed to be replaced. Instead of reacting, a second opinion was sought that confirmed the tire tread was deteriorating or wearing. Noting that the vehicle mileages at purchase was approx. 23,000 miles and had approx. 27,600 miles in January, plus quality tires should last 50,000 to 60,000 miles assuming normal driving conditions, the tire condition seemed abnormal. Another fact was the second opinion revealed the tire’s manufacturing date in 2020, which also does not seem proper. Upon contacting Sales Manager, Operations Manager and Service, another set of tires were installed and aligned at no cost.

Best experience and fastest total transaction I’ve had in
Best experience and fastest total transaction I’ve had in my car buying experience. From the easy access to the dealership off the West Side Highway, to the amazing environment they’ve created inside, to sales consultant Gregory Gazzola’s expertise and ability to read a customer and deliver the vehicle I wanted, at the price I could afford, expeditiously, it was absolutely the best experience. I emailed Gregory this morning, he found me a vehicle, presented a deal, and gave me a pick up time for earlier this afternoon. I was in and out of the dealership in less than an hour today – I’ve spent more time in Home Depot buying a grill. I highly recommend Mercedes-Benz of Manhattan and Gregory.

I saw an SUV online @ RT46 Mitsubishi in Totowa NJ.
I saw an SUV online @ RT46 Mitsubishi in Totowa NJ. that want to see. I saw a salesman named Omar about it. He acted fast told me to take it for test drive. Once I got back we started talking price that I can afford. He was so professional on answering all my questions too, and the management team handled it all themselves too.I felt comfortable since the first walk into the dealer. I was offered coffee and thoutgave out bottles of water.. I'm happy with my Jeep I purchase. I give Onar and his team 5 stars. So if your looking for a vehicle new or used give RT46 Mitsubishi a call and ask for Omar.

My regular service advisor was not on duty so I was
My regular service advisor was not on duty so I was greeted by Michael D’Loia who precisely understood that I didn’t want tire rotation service because I had a tire contract elsewhere and that I wanted the air filter I purchased elsewhere to be installed and I would only pay for the install. Also, I wanted the old filter(smile). He graciously noted my requests and after my car was ret’d all of my specifications had been followed. Radiator flush, transmission service, oil change and a free car wash. I was very pleased with Michael’s recommendations and my car runs smoooothly. Thank you Lynne’s Nissan
